Abstract

Only the stator discs 22 of the multi-disc brake are provided with grooves for the radially inward flow of liquid coolant from inlet passage 28 to outlet passages 32c the surfaces of rotor discs 20 are smooth to prevent their producing a centrifugal pumping effect. The brake includes a non-rotating outer housing 14, a centrally disposed drive shaft 13 extending through the housing 14, a plurality of axially moveable stator and rotor brake discs 22, 20 and a fluid actuated piston 24 for squeezing the discs together, the passage 28 being defined by a portion of the non-rotating housing disposed about the outer periphery of the stator and rotor discs.
